Long ago, when I was first developing the Shaded Basecoat technique, this is one of the units that I was working on. At that point, I had mixed white primer with my paint to make the "lighter than needed" colors, and still do the priming stage too.
Now that I have the airbrushes and the various colors of primer from Badger, it would be a lot easier to do this today! These guys were tucked away in a box somewhere, forgotten for almost 10 years.
I also didn't have the access to the fantastic glazing colors such as the Reaper Clear paints, or the Vallejo washes. It's always interesting to look at very old pieces like these, and notice the differences. It has more to do with the approach vs the final result.
My current approach would let me focus more intently on the subtle color shifts in the shadows and mid tones, where years ago the establishment of highlights was the primary goal.
